Overview

• In its third assessment published September 3, the Cour des comptes says the reconstruction met the five‑year timetable with costs kept under control.
• Roughly €843 million in donations financed the work, with a concluding €140 million phase to address pre‑fire pathologies and complete the restoration funded by major patrons.
• Annual operating outlays are expected to about double to roughly €5.2–€5.27 million due to enhanced security, fire protection and visitor management needs.
• The ad hoc authority EP‑RNDP, credited as key to the project’s success, is slated to wrap up by end‑2028, and auditors call for a detailed transition and long‑term maintenance plan.
• The report notes new fire‑safety systems, including roof misting and a 24/7 staffed control center, and urges a national standard for handling lead on heritage sites.
